Hi!
Finally, after the last update of the W3All, the problem seems to be definitely resolved!

Thank you for all

hey! well, it is only a cookie problem, and i'm just over for the time i can, to prepare 1.7.6.
So after a report at wp.org forum about problems on login WP that loop, i've try several check to see all is in order.
1.7.5 has been patched 3 times (one right now, to resolve a php notice error on certain logout function call, that by the way was not a big fix, while others previous two, are quite important, so please update to the very latest re-downloading the two updated files, which are
wp_w3all.php
and
class.wp.w3all-phpbb.php
https://plugins.trac.wordpress.org/brow ... tion/trunk
and replace, or just download the 1.7.5 plugin and replace all files.

In the while i was testing, i've encounter the same problem you've report: blank page at phpBB ACP login.
It has happen, because i've change to wrong for test the cookie setting on ACP, so, i've logout phpBB, and try to login: on front end all ok, at ACP, blank page.
So, i've check what was happening with cookies: old cookies was existing on browser, and also the new one of the new session with new setting.
So, i've cleanup all cookies and re-login.
Nothing to do, because the cookie setting on phpBB acp was wrong. blank page.
So i've login to db, changed the cookie setting to the good one directly on config db table:
i've clean cookies, i've login phpBB frontend, than to ACP ok.
The blank page on ACP, is definitively a problem about cookies and sessions that are recognized in wrong way somewhere, in certain conditions (may because you have change the setting in phpBB about cookies, than when you do logout, the old, because the new setting is active, isn't deleted, and i suppose, by the way it is recognized as valid in phpBB when try to login (while this not happen in frontend) ACP. Maybe this conclusion is totally wrong, may not .... by the way ...

i'm over to check further problems about cookies, and a loop in WP when WP is called via url like
http://mydomain.com
instead than www.mydomain.com
(if it is the setting in WP about site url: i've test in this way but i suppose should be the same problem if the setting is contrary)

Still i've not understand by what it is caused, but as resolved, 1.7.6 will be released, due the all above that is already fixed, and something more ...

Hi axew3,

sorry for the late reply.
Finally, I managed to get into ACP but with a trick.
I log in within the site, I go to the forum, I go to the ACP login form and, at this moment, using the Chrome developers tools, I stop all the cookies except those of phpBB.
I insert username and password and I get into ACP!!!
This doesn't mean that the problem is solved but it's already a step ahead.

Thank you

ah ok! This look like a problem in phpBB only.

So, have you try to clean up cookies into your browser, so re-login?
At this point i think yes with no lucky, or not?

To purge the cache manually, since you can't access ACP:
on phpBB 3.1:
How to purge your cache manually 3.1
Access your FTP server (or other method to access files)
Navigate to the /whereyouinstalledphpbb/cache directory
Delete all files except for the index.htm and .htaccess files (the .htaccess file may not be visible)
You're done!
as explained here: https://www.phpbb.com/support/docs/en/3 ... pbb-cache/

WHILE for phpBB 3.2 you may do this:
navigate to folder:
/yourphpBB/cache/production
and DELETE all files contained inside this folder (do not delete the folder).
OR better, just to be sure you can after restore in case, maybe rename the folder production into
production_off
so create a new empty one, named production inside the cache folder
(than you can restore with easy the old one with his content whenever necessary)

When you've update your phpBB, have you perform the step about update of the database, and this has been finished without any error?

Cookie domain seems to be ok and so the path.

The problem happens by accessing the forum both via site and directly. I mean that even if I access to the forum via www.mydomain.org/forum I get the same issue.
purge the cache from the admin panel main page
Which "cache" do you mean? And which "admin panel" do you mean?
The forum "cache" and the "admin panel"?
I cannot access the forum admin panel, that's the problem!!! :(

Thank you once more

This both if I reach the forum via site and if I reach the forum directly with a "/forum" in the adress.
mh ... sorry, this mean, it happen if you open it via WP page (so iframe) or direct url to phpBB, so on both cases, or what?

Have you try also as suggested on linked post, something like this?

The problem could be your cookie settings.

cookie domain: yoursite.com
should be : .yoursite.com ( the dot in front )
cookie path should be : / ( just the slash, nothing else )
change that from the admin panel cookie settings.


If the above is already ok for you as i think, than just:

purge the cache from the admin panel main page
CLEAN cookies from your browser (i've add this step)
refresh your browser to get the new cookie.
Login
